Abstract
The utility model discloses a self-cleaning liquid-level detection box, consists of a box body (1), a probe (2), an insulator (3) and a controller member (4), and is characterized in that the side surface of the probe (2) and the top of the box body (1) are provided with water-spraying pipes (5). The water-spraying pipes (5) are provided with water-flushing orifices (8)at the locations near to the probe (2). The utility model can effectively clean the crystallized lithium bromide on the insulator (3) and the probe (2) under the circumstance of not damaging the internal vacuum of the machine and the normal operation of the machine, and is suitable for various high-pressure generators of the lithium bromide absorption-type water heaters and chillers.
Description
Technical field
The utility model is about lithium bromide absorption cold (heat) water unit, more particularly, is the Level Detection case about the high pressure generator of lithium bromide absorption cold (heat) water unit.
Background technology
Present lithium bromide absorption cold (heat) water unit comprises direct combustion type, steam type, hot-water type.This unit is when operation, and the liquid level of high pressure generator Level Detection case can change with the variation of running status, normally moves in order to guarantee unit, liquid level must be controlled in the suitable scope.For this reason, just must respond to the variation of actual liquid level at any time, and the signal that this changes is at any time passed to control system, carry out adjustment at any time by the topworks of control system again liquid level.
Level Detection case commonly used as shown in Figure 1.Can settle several probes 2 as required in the casing 1, utilize the electric conductivity of lithium bromide liquid, liquid level is contacted with the probe 2 of different length, form the closed-loop path, produce corresponding current signal, this current signal passes to control device 4, starts topworks by control device 4 again liquid level is adjusted.But in actual motion, because the working temperature of Level Detection case is very high, can reach 150 ℃, therefore can make the violent lithium bromide liquid splash of fluctuation on insulator 3 and probe 2,3 in the insulator that is stained with lithium bromide liquid can lose insulation function, very easily forms partial short-circuit with casing 1.In addition, the lithium bromide liquid that sticks on insulator 3 and the probe 2 is understood Yin Gaowen and is formed crystallization and difficult drop-off, and therefore, control system will be sent false liquid level signal, makes control malfunctioning, and then the initiation unit produces other fault.
The method of traditional removing crystallization be with probe 2 by taking out in the casing 1, treat to be reinstalled again after the wiped clean, so both destroyed the unit vacuum, must stop unit operation again, also to wait until when fluid temperature is reduced to 60 ℃ of left and right sides by 150 ℃ and could operate.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, a kind of simple in structure, easy operating is provided, neither influences the high pressure generator Level Detection case that unit normally moved, do not destroy again the unit inner vacuum, can effectively remove the lithium bromide crystallization on insulator 3 and the probe 2.
Self-cleaning high pressure generator Level Detection case of the present utility model comprises casing 1, probe 2, insulator 3 and control device 4, and the upper end of the side of described probe 2, casing 1 is provided with sparge pipe 5.
Described flush port 8 is the groove shape
Described flush port 8 is poroid.
One end of described sparge pipe 5 is a closed, and the other end is provided with Draw off valve 6 and feed pipe 7.
One side of described probe 2 is provided with a sparge pipe 5.
The both sides of described probe 2 are provided with two sparge pipes 5.
The beneficial effects of the utility model are normally to move, do not destroy again under the situation of unit inner vacuum not influencing unit, can effectively remove the lithium bromide crystallization on insulator 3 and the probe 2, have simplified operation, have improved the running quality of unit, have saved the energy.

Fig. 2 is the liquid level control of the utility model self-cleaning high pressure generator Level Detection case and removes the structural representation of crystallization.
Main part mark explanation among the figure:
1---casing 2---probe
3---insulator 4---control device
5---sparge pipe 6---Draw off valve
7---feed pipe 8---flush port
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Self-cleaning high pressure generator Level Detection case of the present utility model, comprise casing 1, probe 2, insulator 3 and control device 4, the upper end of described probe 2 sides, casing 1 is provided with sparge pipe 5, and a side of probe 2 or both sides are provided with 1 or 2 sparge pipes 5.Sparge pipe 5 is provided with flush port 8 near the appropriate location of probe 2, and flush port 8 can be designed to the groove shape as required or be poroid.The one end sealing of sparge pipe 5, the other end links to each other with feed pipe 7, and the centre is provided with Draw off valve 6.
When false liquid level signal takes place owing to the lithium bromide crystallization in the Level Detection case, can open Draw off valve 6, the pressure that utilizes the unit cryogenic fluid pump to produce is sprayed water by feed pipe 7 water as refrigerant (pure water of unit inside) by the flush port 8 of sparge pipe 5, until insulator 3 and probe 2 are cleaned up, get rid of false liquid level signal.
